Made from scientifically proven active ingredients

ID-alG™

1. ID-alG™

ID-alG™ is an extract of the brown seaweed Ascophyllum nodosum, which is rich in long-chain polyphenols called phlorotannins. They help to inhibit the action of the two main digestive enzymes, lipase and amylase, and block up to 77%* of carbohydrate digestion and 63%* of fat digestion.

L-Carnitine

2. L-Carnitine

L-carnitine is an amino acid that is crucial for fat metabolism because it ensures that long-chain fatty acids are transported to the mitochondria where they are converted into energy.

L-Tyrosine

3. L-Tyrosine

L-Tyrosine contributes to the normal synthesis of catecholamines, including adrenaline, noradrenaline and dopamine.

Vitamin C

4. Vitamin C

Vitamin C contributes to the protection of cells from oxidative stress and is also essential for the formation of collagen.
